Are there any useful to these shell folders?
My interest to them is that it contains the word shell which remind me of shell32.dll file. I used the shell32 file to change icon appearance. I want to change my game folder to look like one of the game icons but then I realized shell:games is not a dll or file.

The appdata folder in the User Profile is just a container folder of the 3 special appdata folders. It isn't a special shell folder in any way.
You should never need to just open it. If you want to though you can use the path shell:UsersFilesFolder\AppData to get there.
I would recommend just using the paths for each of the 3 special appdata folders instead:
Roaming - shell:AppData
Local - shell:Local AppData
LocalLow - shell:LocalAppDataLow

Microsoft should have named shell:AppData something like shell:AppData Roaming instead but they did not.
If I ever get around to making a list of weird things done in Vista for no apparent reason I will add this to it.

Since finding out from the other thread that some shell: shortcuts work on I Windows XP I decided to make a list of which work on Windows XP and which require Windows Vista.
I also decided to sort them into categories of Virtual folders, per-machine folders, per-user folders and unopenable folders.
I also added a short description.
It took longer then I thought it would so they don't have the best descriptions.
The list is at http://www.techoddity.com/howt.....shortcuts/

I have Vista search indexing disabled so using the search in the start menu is not an option. If I use a command prompt then stuff like C:>start shell:personal will work but C:>start shell:Quick Launch or C:>start "shell:Quick Launch" or C:>start shell:"Quick Launch" will not. Tried all kinds of quoting. Do you know the trick? Also is it true that Osama bin Laden was the guy who decided to ruin our civilization by allowing spaces in paths in Windows? :)
